A Third-Party Payment Service Provider, or TPP, is an authorised Payment Service Provider (PSP) that is able to access customer accounts and conduct transactions on behalf of businesses. The concept, Third-Party Payment Service Provider, is emerged from the Open Banking framework and is designated in PSD2.

● Payment Initiation Service Provider (PISP): A PISP enables customers to make online payments using their bank accounts, no credit card or debit card is necessary for payments.
● Account Information Service Provider (AISP): An AISP enables institutions to access “read-only” financial data of a user or SME.
